AIDA64 Random Access Time

AIDA64 offers several different benchmarks for testing and optimizing your system or network. The Random Access test is one of very few if not only that will measure hard drives random access times in hundredths of milliseconds as oppose to tens of milliseconds.

Drives with only one or two tests displayed in the write test mean that they have failed the test and their Maximum and possibly their Average Scores were very high after the cache fills. This usually happens only with controllers manufactured by JMicron and Toshiba.

On release, the Vertex 4 512GB had a big advantage over the V3 480GB in access time, but after the 1.4RC release the two seem to be pretty even. The Phison and Marvell controlled drives from other manufacturers did do a little better in this test, though.

The write latency for the Vertex 3 is in line with other SandForce based drives. The write latency and the IOPS that goes with low write latency is where the Vertex 4 really outshines just about every other SSD on the market.
